Hello,
1) I’ve just checked menu and it’s working perfect. Please see screenshot: http://prntscr.com/76kt1z
2) Please try to add this code in custom.css file
.page-id-15612 .vc_col-sm-6.wpb_column.vc_column_container {
position: initial;
}
3) As I see search options working fine. Could you please clarify us with more details?
Regards,
Robert Hall.
